User Manual — GNUnet documentation

# User Manual

This tutorial is supposed to give a first introduction for users trying to do something real with GNUnet. Installation and configuration are specifically outside of the scope of this tutorial. Instead, we start by briefly checking that the installation works, and then dive into uncomplicated, concrete practical things that can be done with the framework provided by GNUnet.

In short, this chapter of the “GNUnet Reference Documentation” will show you how to use the various peer-to-peer applications of the GNUnet system. As GNUnet evolves, we will add new sections for the various applications that are being created.

Comments on the content of this chapter, and extensions of it are always welcome.
